WILLIAM v. TAZBER, or NOT, MISSOURI FLUE-CLEANER.

Specification of Letters Patent. Patented Sept. 1 9, 191 1.

Application filed February 8, 1911. Serial No. 607,227.

To all whom it may concern:

Be it known l, VVILLIAM V. TABER, a citizen of the U id States of America, residing at Not, it e county of Shannon and Shite of Misso: L, have invented new and useful Improvements in Flue--Cleaners, of which the following is a specification.

This invention relates to flue cleaners, and has for an object to provide a device of this character including yieldingly supported radially extending scraping blades or elements and to provide means for adjusting or moving the blades radially and into effective scraping contact with the flue.

In the drawings, forming a portion of this specification and in which like numerals of reference indicate similar parts in the several. viewsz-Figure 1 is a section through a portion of the fine showing my improved cleaner therein. Fig. 2 is a longitudinal section through the cleaner on line 2 2 of Fig. 1. Fig. 3 is a section on line 3--3 of Fig. 1. Fig. 4 is a section on line i t of Fig. 1. Fig. 5 is a perspective view of one of the scraping blades.

My improved scraper comprises a cylin drical member 1 which is formed atone end to provide a head 2 having an opening 3 therein fora purpose to be hereinafter described. The opposite end of the member 1 is formed to provide a bayonet slot 1 in which the pin 5 of the sleeve or bushing 65 is removably fitted. This sleeve or bushing formed to provide a threaded passage 7 in which the correspondingly threaded surliace 8 of the adjusting member 9 is engaged.

The member 1 is formed at or near its center with a plurality of radial substantially elongated or rectangular slots 9 in which the stem portions 10 of thc'scraping blades or segments 11 are fitted and adapted for movement radially of the member-.1 The segments or scraping blades 11 are identically constructed and each is yieldingly supported by a plurality of flat leaf springs 12. These springs extend in opposite directions to each other and their inner ends are bolted or otherwise suitably secured, at 13, tothe scraping blade. The opposite ends of the springs are bolted or otherwise suitably secured to'the member 1,

as at 1 1. The springs 12 exert their tension to hold the blades 11 normally at the innermost extent of their movement so that the inner extremities of -the stems 10 are arranged wholly within the cylindrical memher and directly in the path of movement of i the beveled or substantially conical surface 15 on the \intermediate portion of the adi member 9 is formed to provide a relativelylong reduced guide stem 18 which is movable in the opening 3 in the head 2 of the member 1.

From the construction described it will be seen that the clczflner may be arranged within the flue andthe adjusting member operated so as to obtain the desired expan--,

sion of the scraping blades or elements 11 so that, the combined diameter of the blades will be equal to the internal diameter of the flue, causing the flat scraping surfaces of the blades to be moved yieldingly into etlective scrapin contact with the innerv surface of the due. After the desired adjustment of the blades has been obtained the cleaner may be reciprocated within the flue by any suitableineans. By providing the detachable bushing or sleeve 6 at one end of the cylindrical member I provide for the intercluuigeable association therewith of similar bushings each having an opening of a ,dificrent diameter so as to accommodate adjusting members of different sizes, accordin to the expansion of the blades 11 desire. The cylindrical member 1 is formed with an exteriorly threaded portion '19 to which may be fitted any well known form of socket or chuck of the tool employed for moving the cleaner loi'igitudinally in the flue. The position of the threaded portion 19 with respect to the bayonet slot 4 is such that when the coupling socket or chuck of the tool is engaged -with the member 1 it will entirely close the slot 4 and thereby prevent any possible disconnection of the bushing or sleeve 6 from the member 1 when the latter is moved longitudinally in the flue.

I claim:

1. A flue cleaner comprising a membciya plurality of blades supported by the memher and movable radially thereoflthe said blades having portions extending into the a bushing removably fitted to the opposite end of the member, a blade-adjusting member movable longitudinally in the member and having a portion slidably fitted in the head and having a portion threadedly fitted in said bushing, and a substantially conical surface formed on the adjusting member intermediate of the ends thereof and 0 erating to engagethe inner ends of the blades so as to move the ibladesradially on movement, of the blade adjusting member.

A flue cleaner com rislng a cylindrical member, a plurality of, ladessupported b the member and movable radially thereog the said member having a bayonet :slotformed therein at one end and having an g exrel-iorly threaded portion, adjacent to the member, a head at one end of the member,

the bayonet slot, and a 20 said slotya sleeve removably fitting in the said member at one end thereof and provided with a pin for lockin engagement in:

ilade actuating member a'djustably conneeted with the 25 sleeve and movable longitudinally inv thew cylindrical member and provided with means for "actuating the scraping blades for moving them radially. M

1 In testimony whereof I. aflix my sigma- 30 ture in presence of two witnesses.
